Type Occurrence of GrumipluciteHide

General Appearance of Type Material:
Very slender grey-black prismatic crystals, with a metallic luster and almost micaceous (001) cleavage. Crystals are elongated according to [010] and are twinned on (001).
Place of Conservation of Type Material:
Museo di Storia Naturale e del Territorio, Pisa University (n° 4262).
Geological Setting of Type Material:
Quartz veins in a small mercury deposit hosted within phyllitic and metavolcanic rocks of Middle to Upper Ordovician, intensely deformed and metamorphosed to the greenschist facies. Low-temperature, formed in low-f(S2) conditions.
Associated Minerals at Type Locality:
Reference:
